Q. Choose the correct statement among the following
A) $\Psi^{2}$ represents the atomic orbital
B) The number of peaks in radial distribution is $n - l$
C) A node is a point in space around nucleus where the wave function $\Psi$ has zero value
D) All of the above
Explanation
(d)
$\Psi^{2}$ is a probability factor. For hydrogen wave function, number of nodes (the space where probability of finding electron is zero) can be calculated as
Radial nodes $= (n - l - 1)$
Angular nodes $= l$
Total number of nodes $= (n - 1)$
